Google Sheets ported its calculation worker from JavaScript to WasmGC
Calculations in Google Sheets were initially done on the server, then on the client in JavaScript, and now on the client in WebAssembly Garbage Collection. This case study explains how and why.
To ensure that the JavaScript calculation engine produced precisely the same results as the Java version, the Sheets team developed an internal validation mechanism. Sheets, a part of Workspace, was identified as an ideal candidate for evaluating WasmGC: it is performance-sensitive and has robust performance and correctness validation mechanisms.
